6/10 imo
It had some good moments. Some hype moments. But a lot of places where the writing was just kinda ass. Wano was the culminations of 10 years of post timeskip one piece. This should have been the manga equivalent of Avengers infinity war and endgame.
But it just wasn't. The execution really wasn't the best.
The supernova trio and Zoro especially had really messy writing (ex. Zoro's lineage, Nika fruit asspulls, ect.)
The oden flashback was profoundly contrived
Oda couldn't even give us proper Kaido/Big Mom rocks flashbacks because he needs to save it for the future to preserve hype
The SHs feel like side characters in their own story
There was literally no tension during the war. The two major deaths, Ashura and Izo, meant absolutely nothing because Oda puts in so many fake deaths that nobody even believed they were dead until it was confirmed. Like really man, you just had to revive pound in a cover story? I swear to god, I cannot fathom how Oda writes bullshit like this. This is a major war arc, and Oda couldn't even pull off one meaningful death.
I guess Hawkins's death is pretty good, but who knows? it was never confirmed. Fucking Loda could reveal next chapter that Chopper, Marco, or Law saved him right after he passed out.
